Abstract

Weed scientists regularly attend conferences, symposiums, and workshops to communicate with colleagues about their current weed research programs. Communication of research can be hindered by poor visual aids. Computer programs, film recorders, and color printers have greatly increased the ease of visual aid production but have also increased the opportunity to prepare incomprehensible presentations. The size of the text, the amount of information presented, and the contrast between the text color and background color are the most important factors that affect the legibility of visual aids. Text, tables, and graphs should be short, simple, and legible. Computers and film recorders are not essential to produce good visual aids. The greatest assets in the production of visual aids are common sense, familiarity with the production equipment, sufficient preparation time, and critical assessment of the visual aids well in advance of the presentation date.
